Roger Ebert, the famed Chicago Sun-Times critic whose namesake website is an interactive portal for movie reviews and news, died in April after a long battle with cancer. He was 70.
Seitz, who lives in Brooklyn with his two children, is a filmmaker and TV critic for New York magazine and Vulture.com.
"It was critically important to me that the editor-in-chief for RogerEbert.com have deep, high-touch experience in the world of film-making as well as film criticism. Matt is the total package," Chaz Ebert -- Ebert's wife, the owner of Ebert Digital and publisher of RogerEbert.com -- said in a statement Tuesday. "Roger and I envisioned the site as a bridge between critics and fans. Matt brings his own loyal followers and fans to help build on Roger's enduring legacy."
